What Is Geology? Geology is an earth science concerned with the solid Earth, the rocks of which it is composed, and the processes by which they change over time.

What Is Geology?

Geology can also refer generally to the study of the solid features of any terrestrial planet (such as the geology of the Moon or Mars). Geology gives insight into the history of the Earth by providing the primary evidence for plate tectonics, the evolutionary history of life, and past climates. Geology is important for mineral and hydrocarbon exploration and exploitation, evaluating water resources, understanding of natural hazards, the remediation of environmental problems, and for providing insights into past climate change.

Geology also plays a role in geotechnical engineering and is a major academic discipline. Mapping & Fieldwork Field mapping:Geologists traditionally record in field notebooks their observations, including sketches, measurements (for example, the angle of tilted strata), and narratives.

Rock stars: Geologists on the silver screen

Cantner, AGI. By: Erik Sturkell, Axel Sjöqvist, Lennart Björklund and Andreas Johnsson When geologists gather for a beer after work or around a campfire after a long day in the field, the conversation sometimes turns to how our profession is portrayed on film. Are geologists heroes or villains? Do they appear only in supporting roles — their parts limited to entering an office, uttering “Drill here,” and promptly leaving the scene — or are they main characters? Michael Easton of the Ontario Geological Survey and colleagues addressed some of these points in a 1990 article, “Hollywood’s Portrayal of Geologists: Earth Scientists on Celluloid,” in the pages of this magazine, then called Geotimes. This stands in stark contrast to the customary film portrayals of physicists and chemists. Much has changed in the last few decades, however, so we decided to reexamine the question of how geologists are portrayed on film, incorporating movies released since 1990.

I’m sure you all remember where you were when you found out that the statistical correlation of magneto-biostratigraphic calcareous nannofossils with M-sequence magnetic anomalies approximated new boundaries for Tethyan Kimmeridgian of Sardinia (Muttoni et al. 2018).

What is geologic time, and how does it work?

I was on my laptop at the time. I’ll confess, I struggle to even begin to understand what this new paper is about, beyond the broad principle that a chunk of the rock record as it relates to geological time is being slightly tweaked. The Kimmeridgian is a stage of the Upper Jurassic series – the last series in the more-famous-than-most Jurassic System.

We are talking, of course, about the geological time scale, the ridiculously complex scale we use to describe and divide the history of the Earth into different sections. Unlike the periodic table, despite the fancy sounding magneto-biostratigraphic techniques used to create the geologic time scale, it doesn’t really mean a great deal. Now that's what I call bioturbation!

The English Language: A Natural History by Dr Haydon Mort. What are Ripple Marks? Ripple marks are sedimentary structures and indicate agitation by water (current or waves) or wind.

What are Ripple Marks?

Ripple marks are ridges of sediment that form in response to wind blowing along a layer of sediment. Ripple marks form perpendicular to the wind direction and each ridge is roughly equidistant from the ripple mark on either side. The troughs and ridges of fossilized ripple marks in sandstone and siltstones are hardened versions of the short-lived ripples in the loose sand of a modern-day stream, lake, sea, or sand dune. Ripples may be made by water or, in sand dunes, by wind. The symmetry of water-current ripple marks indicate whether they were formed by gentle waves or faster water currents. There are two types of ripple marks: Symmetrical ripple marks Often found on beaches, they are created by a two way current, for example the waves on a beach (swash and backwash).

Asymmetrical ripple marks These are created by a one way current, for example in a river, or the wind in a desert. Tissue & foam to make minor folds.
